Failure to adhere to these safety

instructions may result in damage to the

product or serious bodily injury.

RoHs

Our products are RoHs compliant.

Battery disposal

The batteries contained in our products need to be disposed of as per your

local legislation acc. to EU directive 2006/66/EG.

3. BEFORE PUTTING INTO OPERATION

Please check that the technical data of the installation match with those of the lube meter, for example connections, pressure,

flow range and medium. Once the meter has been installed, please make sure that no air, pressure shocks or particles can

damage the meter.

Read the following information and have a thorough understanding before proceeding with meter installation. Only

qualified personnel should perform meter installation.

• Install a strainer or Y or basket as close to the inlet side of the meter as possible. Strainers prevent dirt and other fluid

contaminants from impeding meter performance. Strainers require periodic cleaning, as clogged strainers also impede

meter performance. Contact your local representative for specific information, per your specific application.

• Turn off any associated pumps to reduce line pressure and slowly fill the line and meter with fluid before restarting

pumps. Doing so reduces the possibility of meter damage caused by errant air pressures in the line and meter.

• Make sure all pipe conforms to the same pressure output rating as the pump.

• Make sure to apply thread sealant to all pipe threads.

• Make sure to install the meter as shown in figure 1.

• Check for and repair leaks upon initialization of fluid flow.

3.1 Recommended filter sizes

Filter / Pore size (in mesh)

Filter / Pore size (in mm)

½"

0,250

Please check all connections to leakage. After the installation we recommend to perform several transactions into an

approved piston. Should the use of different oil viscosities show discrepancies by the error limit, it can be immediately

corrected at the site. The pretested meters can be calibrated by technicians or the officials of the national authorities (MID).

Details of unit operation LM OG-AM series

Page 4 LM_OG-AM_BA_02_1163 May 2019

5. DETAILS OF UNIT OPERATION LM OG-AM SERIES

5.1 RESET button

The display of the resettable totalizer (batch register) can be put to zero by pushing the RESET button. A RESET is not

possible during a batch process. The RESET of the non-resettable totalizer is only possible in the MID secured area of the

register configuration. Each RESET will save the dispensed quantity in the datalogger, but only if the quantity is equal or

bigger than 0,5 liters.

5.2 Datalogger: A non-volatile memory

The register is fitted with a memory device to store measurement results until their use or to keep a record of commercial

transactions, providing proof in the event of a dispute. Devices used to read stored information are considered as included in

the memory devices. It is not required that the parties interested in a transaction shall be provided continuously with the

results of measurement, but only that they shall have access to these results (for example, in the event of a dispute). In

addition, in the case of self-service (filling station, truck filling station) the owner of the measuring system is considered to

have access to the indications of the measuring system even when he does not use this possibility in practice (OIML R117-1,

Chapter 3.5).

5.3 Battery

As soon as the capacity of the battery is less than 10%, “LBat” is displayed on the electronic

exchangeable in all meters of the LM OG-AM and OG-TAERM series while opening the cover

on the front of the register. No data are lost, they are securely saved in an EEPROM memory -

except of the date and time. To keep the date and time settings, you have to reinsert the

battery within 30 minutes. See also chapter 13.

5.4 Interruption of batch process

By releasing the meter trigger, the batch process is interrupted. When pulled again, the batch process will be continued at the

very point where it was interrupted, unless the RESET button has been pushed in the meantime. The display will remain

unchanged during the interruption. If the batch process is interrupted by external source – e.g. failure of a transfer pump – the

procedure is the same.

5.5 Functional control

In normal operation, the register board totalizes flow in the lube meter by sensing reed switch actions. The batch display may

be reset to zero by momentarily pressing the RESET button on the front panel. This action will set the batch accumulator to

zero and cause the register to enter a self-test mode. For the self-test, it is necessary that the display is activated with all

numerics set to “8” and all other indicators set to “on” for a period of 0,8 seconds. If flow or reed switch action takes place

during the self-test period, the resultant pulses are processed as normal flow accumulations. This accumulation of flow can

only be reset by pressing the RESET button.

During the self-test period, the meter will compare the double redundant storage of the correction factor, the unit of measure

and direction of rotation. If one of the values do not correspond, the register will show a series of dashes (- - - -) and will

become inoperative.

If flow sensing or reed switch action is present at any time and it is not preceded by a pressing of the RESET button, the flow

accumulations will be added to the value already present in the batch accumulator.

5.6 Totalizer

The total dispense quantity is shown in the bottom line. The factory programmed correction factor results from accuracy

testing of bare meter with the mounted electronic register: Pressing the TOTAL and the RESET button simultaneously for 3

seconds will show the programmed correction factor.

Resettable totalizer: 999,999 L (over thousand 9999,99 L)

Non resettable totalizer: 99999 L

As soon as volume signals come in, all keyboard commands will be ignored!

As soon as pulses are internally accumulated, the keypad is out of function!

5.7 Monitoring of false pulses for MID conform meters

During measurement, the microprocessor controls the phase position of both reed switches (30° to 150° phase shift).

Errors caused by incorrect phase sequence:

If more than two (2) phase errors are noted after a RESET, the LCD display is flashing (1 second interval). This type of error is

resettable by depressing the RESET button.

If it is not possible to stop the flashing, there is another fault and the register has to be exchanged.

The flashing can e. g. also be caused by a short-time reverse flow when starting up the oil dispense system, or by an

insufficiently areated oil pipe (pressure shocks). This can be prevented by installing an appropriate non-return valve.

FLDIR will indicate a reverse flow, quantity display will change to ---,--

REED will indicate a missing input channel, quantity display will change to ---,--

Errors in stored variables:

(i.e. correction factor, unit of measure, direction of rotation)

These errors are indicated by a series of dashes across the display and are not resettable. The register has to be removed from

service.

5.8 Installation procedure LM OG

The meter series LM OG is equipped with BSP female threads. In order to obtain a leakage-free connection from the meter to

the hose, the hose end must have an appropriate BSP male thread.

We recommend to proceed as follows before screwing in:

1) Clean both threads from fat.

2) Brush the male thread at the hose with liquid sealant (e.g. Eurolock 310100 or equivalent sealing of other manufacturers).

Be careful that no sealing gets into the meter.

3) Screw both parts together. Do not overtighten the screw connection, otherwise the swivel of the meter could be

damaged.

4) The instruction of the sealing manufacturer should be absolutely followed.

5) The meter mounting should only be carried out by authorized specialist staff.

The right selection of the components as well as the mounting in accordance with the regulations is in the responsibility of

the user.

Calculating the correction factor

May 2019 LM_OG-AM_BA_02_1163 Page 7

7. CALCULATING THE CORRECTION FACTOR

Two different ways are described below to eliminate the existing deviation of a meter.

The reference quantity (“quantity dispensed”) should always be measured with an appropriate measuring device.

• Approved piston or bell prover

• Approved gravimetric method

7.1 Calculation based default settings

Example:

Quantity dispensed: 5,000 liters

Quantity displayed: 4,990 liters

Correction factor k: 4,990 / 5,000 = 0,9980

7.2 Recalculation of an existing correction factor

Example:

Quantity dispensed: 5,000 liters

Quantity displayed: 5,015 liters

Correction factor k: 5,015 / 5,000 = 1,003

The existing correction factor would be for example: 0,9960

Calculation: 0,9960 x 1,003 = 0,9989

The new correction factor is 0,9989

8. PULSE OUTPUT AT REGISTER OG-TAERM

The pulse output on the LM OG-TAERM register has a rating of 2x100 PPL with a 90°-135° phase-shift. Any irregular use or

malfunction will be indicated on the error channel with permanent signal on high. The correction factor will also correct the

output signal.
